This invention relates to theclass of hrushin'g and scrubbing and pertains particularly to'a mop head structureg i I The primary ob'ect of the present invention is'to provide in a manner as hereinafter set forth, an improved mop head designed: to

ir y grip a d ol jmqp. ag, f jfls r'vb- I Another object of theinven'tion is plrotj', a

' vide, in a mannerias hereinafter set 'for mop head of strongand durable construction which can be easily and'quickly manipulated to grasp or release a mop rag.

"'A'stilhfurthenoloject'of the invention is to provide, in a'mann'er as hereinafter set forth, a'resilient'mop rag gripping structure having a spring controll ng a "portion of themark no material departure from thesalient leatures oftheinvention as expressed in the appended cla ms] f In the: drawing?

'versely o the end of the handl and has formed intermediate its ends upon one longitudlnal edge, the short sleeveportion 3 which receives the en d'of the handleand to which it issecured by the rivets orother appropri 'atesecurin elements/t. This sleeve 3 is pro-- I vided at diametrically.opposite points with the laterally projectin sleeve :3 projects is formed to provide the grooveor gutter 6. which is of VI- shaped cross v ears I5. The longitudinal edge opposite t at edge in which the" sectional .designland in which al-portion of the hereinafter described mop' rag gripping [yoke positions a guide ear 7, the utility ofwhich will be seen as the desoript'ion of the structure proceeds. Thehead plate 2 is here shown asformed is of course tobeunderstood that thisplate At each end of the head 2 there'is" formed of a pair of complementary members but, it

may beof solid construction as for example y it may be cast'ina solid piece. I I

Associated withtheheadg is a mop rag gripping yoke indicated as; a Wholeby the I numeral 8. This yoke comprises a straight cross portion9 and the rearwardly extending converging legs 10. The legs 10 of the yoke por tion extend through the guide' ears 7v as I shown and the straight transverse portion i 9 'thereofis designed to normally position in thegroove 6 of thehead 2,

In order to pern'nt M I [I8 longitudinally of-the handle 1v aportlon oi each leg lO adjacent the cross portion 9 is i I i 'm'ade s'traight to extend parallel Withfthe handle. "This permits' reciprocatoryinove ment of the yoke these straight 'port1ons,;

vement of the yoke Whichare indicated by the numeralZ'sliding thro'ugh-thefg'uide 03,137 asshown'. I

, Sl'idably 'mou'nt'edupon the handle 1 is a pair of rings -12 and 13 each o f these rings havin the diametrically oppositely pos tioned outwardly extending headed arms 14 andlfi, These further have fingers 16 i I "formed about the edge'thereof," the'fingers of i one ring being directed toward those of the urroun'ding ithe hahdlei'lfand positioned hetWeeII the rings 12 and 13is'acoiled spring- 1mm. enn e n :t iw x ec f he r 'llwiththe 'I underlying ears il 5 ofxthe rings 13 are longitudinallyslottedconnecting bars 18, the slots of these 'bar s gin "wvhichithe ears are II slidalil ;p os'itioned hehin'd the heads thereof,.i

',beingj1ndi atd by thejnunierals lqif These b irsiz 8 r n h s n fltfrom't m the rings a redeterm ned distance lever member 21 has at each side adjacent the pivotal connection therewith of a toggle arm 20, a longitudinally extending leg 22 which is pivotally mounted upon one of the ears 5 carried the plate sleeve 3.

l/Vhen the mop head is to be opened for the positioning of a mop rag between the bar 9 of the yoke member and the grooved edge 6 of the plate 2, the lever is swung outwardly from the handle 1 to theposition shown in Figure 4, this movement swinging the lower ends of the toggle arms 20 outwardly and pulling down upon the same simultaneously thereby pulling the slotted bars 18 longitudinally of the handle 1 and forcing, the yoke 8 to move in the same direction. will be readily understood this causes the ban por tion 9 of the yoke to move, away from. or out of the slot 6 in the plate 2. After the mop rag has been placed in position across the bar 9 and the lever 21 swung upwardly the reverse of the movement just described will be performed until the bar 9 draws the mop rag tight into the groove 6. Then the mop rag has been tightly clamped between the bar 9 of the yoke and the plate 2 further movement of the yoke 8 longitudinally of the handle will be prevented but this will not prevent the turning of the-toggle arm to a. position substantially parallel with the handle for the lower ring 13 will be forced upwardly to compress the spring 17 against the upper ring 12 thus permitting the lever 21 to be swung back to a position substantially parallel with the handle 1 as shown in Figure 2. From the foregoing description it will be readily seenthat the mop head structure thus described can be readily and quickly manipulated to place a mop rag in position or to remove a mop rag from position and when a mop rag is beingheld by the head it will be secure against displacement.

Having thus described my invention what I claim is: v r

1. In a mop head structure, an elongated plate, means for securing said plate at the central portion of one longitudinal edge to a mop handle to extend transversely thereof, the other longitudinal edge of said plate be ing provided with a groove, guide ears carried by said plate one upon each end thereof, a pair of ring members designed to be traversed by. a handle extending from the plate, laterally projecting ears carried by said rings, a spring element arranged between said rings and normally forcing the same apart, longitudinally slotted bars connecting the ears of onetring member with the ears of the adjacent ring member, a substantially U-shaped yoke having the straight portion connecting the pair of leg portions, said straight portion being designed to extend longitudinally of said plate to position in said groove, said legs-extending through said ears and longitudinally of a handle attached to the plate, and further having their ends connected to the ears otthe ring member remote from the plate, and a lever member carried bysaid plate and having connection with the ears of the ring member lying adjacent the plate and designed, when actuated, to move the ring members, spring and yoke longitudinally' of the handle, substantially as describedj 2. In a mop head structure, an elongated plate, means for securing said plate in the central portion of one longitudinal edge to a mop handle to extend transversely thereof, the other longitudinal edge of said plate being provided with a groove, guidefears carried by said plate one upon each end thereof, a pair of ring members designedto be traversed by a handle extending from the plate, laterally projecting ears carried by said rings, a spring element arranged betweensaid rings and normally forcing the same apart, longitudinally slotted bars connecting the ears of one ring member with the ears of the adjacent rin'g member, a substantially U-shape'd yoke having the straight portion connecting the pair of leg portions," said straight portion bein designed to extendlongitudinally of said p ate to position in said groove, said legs extending through said ears and longitudinally of a handle attached to the plate, a pair of toggle arms connected at one end to the ears of the ring member adjacent said plate, and a levermember pivotally attached at one end to said plate and having the other ends of said tog le arms pivotally connected thereto interme iate the ends thereof and designed, when swung, to shift the said rings, spring and yoke member longitudinally of the mop handle, substantially as described.

3. In a mop, a handle, a cross head secured i to said handle provided with a'pivot ear, an upper and a lowerring on said handle, an

expansion spring confined between said rings,

a bail slidablycarried by the crosshead' for coaction therewith, means connecting the bail with the upper ring, a handle rockably mounted on said pivot ear, and a toggle link 'pivotally connected to said handle intermedi'ate its ends and beyond said pivot point and sp i d- In testimony to the lower ring, as and for the purpose whereof I aflix my signature.
